VTo all whom it may concern:

- Be. it known that I, EDWARD PossoN, a citizen of the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented certain new and uselful Improvements in Car-Trucks, of which the following is a specification.

This invention relatesto an improvement in car trucks and in; particular to an improvement in theV construction of the Vside Yframes of car trucks, whereby ai. stronger,

more rigid, and'more durable construction 1s secured. In car trucks fof the general type now inuse in .freight cars, the truck bolster passes'through between the columnv castings,

'and the latter members are connectedto the arch bars -by means of the usual column bolts only, so that in operation an undue stress is placed upon thesebolts resulting 1n the weakening or breakageof the bolts and y other parts'of the side frame structure. For instance, when the ybrakes are set'on a car coming down grade, the truck is held back and the bolster bears against the forward column so that Jthekentire pressure is transmitted tothe column bolts, causing them to bend backward Vand causingthe top end of the column castings to break out. Furthermore the constant jerking which takes lace through the train, .the unevenness Vo the Y V track and other like causes, operatejto effect a constantpoundingljof the truck 4bolster gainst the top of the column castings.`

.vrilheprincipal object of the present invention is to overcome'the above-mentioned 'difficulty by providing animproved cary truck construction in whichfthe .column castings are supported by other members in 'addition TA further feature castings willv be transmittedv to the other and thereby' distributed tothe slde gframe. A

further feature is the provision of a connecting. member for uniting the upper ends of `the column castings independently of the upper arch bar. `A further feature'is the provision of means whereby theimprovement 1n the mounting ofthe column castings may be embodied in substantially any car truck Specification of Letters Patent. I Patented July 2.7, 1920. Application led July 6, 1917. Serial 1to.`178}890. i

Lthe upper end of one of the columnA castings showing the means for mounting the improved tie bar thereon;

Fig. 4 shows an enlarged vertical section `taken longitudinally of the car through the column casting opposite the one illustrated in Fig. 3;

'f Fig. 5 shows a top plan view of the structure illustrated in Fig. 3; f i

` Fig. 6 shows a top plan view of the structure illustrated in Fig. 4; Aand Fig. 7 showsan enlarged vertical section taken transversely Aof thecar. on the line 7 7 .of Fig. 5.

In' the drawings I have illustrated in Fig. 1 a car truck comprising an upper arch bar 10, a' lower or inverted arch bar 11, and a pedestal tie-bar 12, which are arranged in theN usual manner; as shown. The ends 10a of the upperfarch bar are disposed adjacent and parallel to the ends 11a of the lower arch bar; and the usual journal boxes 13 are adapted to be mounted between the ends 10a of the lower arch bar and the ends of the 'pedestal tie-barV 12, being secured in position Vby means of the journal boX bolts 14. The

car wheels ,15 have their axles journaled in the boxes 13.' The fsidecolumns or column 'castings 16 extendvertically between the central part 10P of the upper archl bar and the ylower central part ofthe inverted arch- ,bar 11j, these parts being normally secured in adjusted position by meansrof the column bolts 17, which" are engaged at their lower ends by, lthe nuts 18. The lower arch bar 'carries' a bolster spring seat 19 having ymounted thereon the bolster' springs 20 carrying the spring plate 21, upon which lis seated the truck bolster 22, which projects between the side columns 16. The side columns are provided with brake hanger carriers 23 which are connected by pins 24 with the brake hangers 25 by which the brake shoes 26 are carried. These features are` parts of a usual car truck construction and are illustrated and described .asa basis for explaining the improvement which constitutes the present invention.

In order to prevent the bending and Weak-r eningr ofthe column bolts 17` andthe break-v age or injury to the upper parts of the columns 16, I have provided a' tie-bar T30 which lies between the horizontal part 10b `ofthe upper archbar and the upper ends of the column '16, as shown in Figs. 1 and 2.

This tie-bar is providedV at its ends with downwardly directedv lugs. or hooks 31,

which engage the outside walls of the col- -umn 16, so -that relative spreading of the upperends ofthe columns longitudinallyof the car is prevented. This tie-bar '30 lies between lthe upwardly directed flanges 32 and theupper vends of the .columns 16, as shown particularly in Figs to'7, inclusive, so thatfmovement ofthe'tiebar transversely of the car isprevented, and, at the samev time, the tie-bar isV held against vertical movement by means of the column bolts 17 which pass downwardly through the upper arch bar, through the tie-bar, and downwardly "through-the column 16.'. The rotation of the column bolt 17 is prevented by means ofmetalv clips or plates A33 having flanges 33 extending over one side ofthe upper arch bar and having ears 33b which may be bent upwardly to engagev one of the YAilat sides of the lsquare heads of the bolts.

In this way the tie-bar 30 is held securely in position, andthe pounding stresses which are received by the column castings 16 from the Atruck bolster are transmitted from. one column casting tothe otherand thus transmitted again tothe truck bolster and other parts of the side frame construction, so that the stress upon the column bolts is relieved, and whatever stress is imparted thereto is divided lbetween the two column bolts of each side frame.

The use of the tie-barBO, in connectiony .arch bars,lrespectively,so that these parts kmay he spaced apart the same distance vertically that the central ypartkof the upper .arch bar is spaced ,from th'exupper ends of `the side eolumns16 by theginterposition of the tie-bar 30.

Although I have shown and described a particular embodiment of this invention for purposes of illustration, it will be understood that it may be embodied in various different forms withoutfdeparting ffrom the spirit of my invention as defined in the appended claims. Y What'I claim 1s:` y
